Using high-quality register data, this paper constructs an empirical portrait of older parenthood in contemporary Norway and explores gender differences in the extent to which older parents are better-resourced parents. Like most family issues, academic and policy discussions of older parenthood have tended to focus on the experiences of women. Although motherhood at older ages was not uncommon in previous generations, rapid social and family changes in recent decades mean that today’s older mother is far more likely to be having her first child. She may have focused on obtaining a good education and then on establishing her career and finding a supportive partner. When viewed through this motherhood lens, older parents are often portrayed as being relatively well-off financially and enjoying stable family lives. Viewed through the fatherhood lens, however, the family literature suggests that age might not be as strong a marker of socio-economic advantage. Our findings show that this is the case: While older fathers are, on average, more socio-economically advantaged than younger fathers around the time their children are born, their relative advantage is narrower than what we observe when older mothers and younger mothers are compared. Gender differences in the family history profiles of older parents appear to explain some of the differentials we document. The children of older fathers are more likely to be born into blended families and less likely to born to a mother who postponed her first birth than are the children born to older mothers. The results suggest that the meaning of paternal age and maternal age differs: paternal age is not as strong a marker of socio-economic advantages and resources for children as maternal age is.

Reports that schizophrenics have older parents than non-schizophrenics (Barry, 1945; Goodman, 1957; Johanson, 1958; Gregory, 1959) are of considerable importance. If valid, they provide evidence for environmental causes of schizophrenia, and by analogy with other conditions where parental age effects have been noted may give some indication of the nature of these causes. There are, however, inconsistencies in these studies: thus Johanson and Gregory found a significant association between advanced paternal age and schizophrenia, but failed to confirm the maternal age effect noted by Barry and Goodman. These differences indicate the need for further investigation and this paper describes such a study.

Offspring produced by older parents often have reduced longevity, termed the Lansing effect. Because adults usually have similar-aged mates, it is difficult to separate effects of maternal and paternal age, and environmental circumstances are also likely to influence offspring outcomes. The mechanisms underlying the Lansing effect are poorly understood. Variation in telomere length and loss, particularly in early life, is linked to longevity in many vertebrates, and therefore changes in offspring telomere dynamics could be very important in this context. We examined the effect of maternal age and environment on offspring telomere length in zebra finches. We kept mothers under either control (ad libitum food) or more challenging (unpredictable food) circumstances and experimentally minimized paternal age and mate choice effects. Irrespective of the maternal environment, there was a substantial negative effect of maternal age on offspring telomere length, evident in longitudinal and cross-sectional comparisons (average of 39% shorter). Furthermore, in young mothers, sons reared by challenged mothers had significantly shorter telomere lengths than sons reared by control mothers. This effect disappeared when the mothers were old, and was absent in daughters. These findings highlight the importance of telomere dynamics as inter-generational mediators of the evolutionary processes determining optimal age-specific reproductive effort and sex allocation.

Individuals within populations vary enormously in mortality risk and longevity, but the causes of this variation remain poorly understood. A potentially important and phylogenetically widespread source of such variation is maternal age at breeding, which typically has negative effects on offspring longevity. Here, we show that paternal age can affect offspring longevity as strongly as maternal age does, and that breeding age effects can interact over two generations in both matrilines and patrilines. We manipulated maternal and paternal ages at breeding over two generations in the neriid fly Telostylinus angusticollis. To determine whether breeding age effects can be modulated by the environment, we also manipulated larval diet and male competitive environment in the first generation. We found separate and interactive effects of parental and grandparental ages at breeding on descendants’ mortality rate and lifespan in both matrilines and patrilines. These breeding age effects were not modulated by grandparental larval diet quality or competitive environment. Our findings suggest that variation in maternal and paternal ages at breeding could contribute substantially to intra-population variation in mortality and longevity.

Abstract Older parents in China rely heavily on their adult children for instrumental assistance. In different multi-child families, multiple offspring may co-operate in providing instrumental support to older parents in distinct ways in terms of how much support they provide on average and how much differentiation exists between them when they provide such support within a family. We aimed to identify different within-family patterns in relation to multiple offspring's instrumental support to an older parent in Chinese multi-child families, and to investigate potential predictors for different within-family patterns. Using data from the China Family Panel Studies (2016), we had a working sample of 5,790 older adults aged 60+ (mean = 68.54, standard deviation = 6.60). We employed latent profile analysis (LPA) to classify within-family patterns and multinomial logistic regression to investigate predictors. Our findings identified three within-family patterns: dissociated (59.10%), highly differentiated (29.60%) and united-filial (11.30%). Older parents in the highly differentiated families tended to be older, mothers, divorced/widowed and to have poorer physical health compared to their counterparts in the dissociated families. In contrast, the composition characteristics of multiple adult children played more important roles in determining the united-filial within-family pattern. The united-filial families were more likely to have fewer adult children, at least one adult daughter and at least one co-residing adult child.

Abstract STUDY QUESTION Do daughters of older mothers have lower fecundability? SUMMARY ANSWER In this cohort study of North American pregnancy planners, there was virtually no association between maternal age ≥35 years and daughters’ fecundability. WHAT IS KNOWN ALREADY Despite suggestive evidence that daughters of older mothers may have lower fertility, only three retrospective studies have examined the association between maternal age and daughter’s fecundability. STUDY DESIGN, SIZE, DURATION Prospective cohort study of 6689 pregnancy planners enrolled between March 2016 and January 2020. PARTICIPANTS/MATERIALS, SETTING, METHODS Pregnancy Study Online (PRESTO) is an ongoing pre-conception cohort study of pregnancy planners (age, 21-45 years) from the USA and Canada. We estimated fecundability ratios (FR) for maternal age at the participant’s birth using multivariable proportional probabilities regression models. MAIN RESULTS AND THE ROLE OF CHANCE Daughters of mothers ≥30 years were less likely to have previous pregnancies (or pregnancy attempts) or risk factors for infertility, although they were more likely to report that their mother had experienced problems conceiving. The proportion of participants with prior unplanned pregnancies, a birth before age 21, ≥3 cycles of attempt at study entry or no follow-up was greater among daughters of mothers <25 years. Compared with maternal age 25–29 years, FRs (95% CI) for maternal age <20, 20–24, 30–34, and ≥35 were 0.72 (0.61, 0.84), 0.92 (0.85, 1.00), 1.08 (1.00, 1.17), and 1.00 (0.89, 1.12), respectively. LIMITATIONS, REASONS FOR CAUTION Although the examined covariates did not meaningfully affect the associations, we had limited information on the participants’ mother. Differences by maternal age in reproductive history, infertility risk factors and loss to follow-up suggest that selection bias may partly explain our results. WIDER IMPLICATIONS OF THE FINDINGS Our finding that maternal age 35 years or older was not associated with daughter’s fecundability is reassuring, considering the trend towards delayed childbirth. However, having been born to a young mother may be a marker of low fecundability among pregnancy planners. STUDY FUNDING/COMPETING INTEREST(S) PRESTO was funded by NICHD Grants (R21-HD072326 and R01-HD086742) and has received in-kind donations from Swiss Precision Diagnostics, FertilityFriend.com, Kindara.com, and Sandstone Diagnostics.

Objectives: This review aims to assess the state of the science around the potential impact of certain patient characteristics on the safety and effectiveness of in vitro fertilization (IVF).Methods: Following Cochrane Collaboration guidelines and the PRISMA statement, a comprehensive systematic review of reviews and recent primary studies examining the impact of paternal age and maternal age, smoking, and body mass index (BMI) on the safety and effectiveness of IVF was performed. Papers, published between January 2007 and June 2014, were independently reviewed and critically appraised by two researchers using published quality assessment tools for reviews and primary studies. Due to heterogeneity across papers (different study designs and patient selection criteria), a qualitative analysis of extracted information was performed.Results: Seventeen papers (ten systematic reviews and seven primary studies) were included. They comprised evidence from retrospective observational studies in which maternal age, BMI, and smoking status were explored as part of secondary analyses of larger studies. The majority of papers found that the likelihood of achieving a pregnancy was lower among women who were >40 years, had a BMI ≥ 25 and smoked. Advanced maternal age and BMI were also associated with higher rates of preterm birth and low birth weight.Conclusions: Based on available evidence, it may be appropriate to consider “maternal age” and “morbid obesity” in public funding policies that aim to maximize the effectiveness of IVF. However, given inconsistencies in the effect of smoking across different pregnancy-related outcomes, support for incorporating it into funding conditions appears weak.

Previous studies have found that although women have higher initial quit rates than men, the quit rates of the two groups converge as time on the job lengthens. This study of personnel records from a large company for the years 1971–80 confirms that finding in an analysis that aggregates observations across all reasons for quits. Disaggregation of the data by reason for quitting, however, reveals marked, systematic differences between men and women. Notably, a higher proportion of women than men left their jobs for non-market-related reasons such as household duties and illness in the family; and women were much more likely than men to name higher wages, and not better opportunities, as a reason for switching jobs. Also, the effects of tenure and education on quit rates differed significantly across both gender and reasons for departure.

As Chinese households are becoming smaller with increasing numbers of adult children and older parents living apart, the extent to which patterns of parental support reflect traditional gender dynamics is under debate. Integrating theories of sibling compensation with ceremonial giving, we tested whether helping non-coresident parents in China is affected by sibship size and how these patterns depend on own and sibling(s)’ gender using a sample of 4,359 non-coresident parent-child dyads nesting within 3,285 focal adult children from China Health and Retirement Longitudinal Study 2013. Opposite to patterns in the United States and Europe, we found substitutions of daughters with sons—having more brothers was associated with daughters’ reduced probabilities and hours of helping. Sons’ patterns of helping were independent of number of brothers and sisters in the family, consistent with the theory of ceremonial giving. These findings reflect the dominance of traditional family dynamics despite changes in family structure.

Abstract Study question Is age a key criteria for characterizing the experience of families in telling donor offspring about the facts of their conception? Summary answer The study shows that, although donor offspring’s age at the time of disclosure has an impact, it is insufficient to describe these families’ experiences What is known already Secrecy was the norm for decades in donor conception, but “openness” has now become the new core value for institutions, professionals and interest groups. Accordingly, in recent years information-sharing practices have shifted in donor conceived families, but a proportion of parents, especially heterosexual couples, still appear to not inform their children about their being donor conceived. Disclosure recommendations seem difficult to apply in practice. A recurring question is: when should children be told? Age is presented as a key criteria: the younger the children are when their conception story is shared, the less of a problem it would create. Study design, size, duration The qualitative social science study includes two sets of semi-directive interviews conducted with 20 French sperm donor conceived adults (April-Dec. 2019) and 22 French parents by sperm, egg or double donation (Feb.-Oct. 2020). Calls for interviews aimed at donor conceived adults and parents by donation were shared on the Internet, in the media (press, radio, television) and through interest groups (PMAnonyme, BAMP!, MAIA) in France. The contact initiative was left to potential participants. Participants/materials, setting, methods Donor conceived participants include 17 women and 3 men conceived 1960–2000 through anonymous sperm donation in heteroparental families. The parent participants include 20 families (20 mothers, 2 fathers) who used donor conception—mainly anonymous (19)—in France, Spain and the Czech Republic starting in the 1980s. 17 conceived as heteroparental couples, 2 as solo-mothers-by-choice and 1 as a same-sex couple. 17 have already informed their offspring of the facts of their conception. Main results and the role of chance The participants’ experiences of disclosure appear to be bound to their historical and social context, especially regarding the prevailing norms on secrecy. Older parents mention having been advised by clinic professionals to keep the facts of their conception from their child(ren). Some also feared the stigma related to infertility. In contrast, some younger donor conceived participants recall the use of a children’s book while being told of their conception as toddlers. Beyond age, the larger context thus affects information-sharing practices. Furthermore, experiences of disclosure are impacted by the family context and history. Some are embedded within larger events such as divorces or the death of a family member. The story of the donation may be linked to narratives of diseases (such as cancer) or traumatic events (such as the loss of a fetus in utero) that may prevail over donor conception or make it untellable. Age proves to be an insufficient criteria to qualify these experiences, all the more so since “disclosure” sometimes unfolds in several steps. Some parents have first talked about their fertility issues without mentioning the use of a donor. Behind the prevailing norm of “openness”, difficulties in actually disclosing are confirmed. Limitations, reasons for caution Being qualitative, the study only includes a small number of participants without claiming exhaustivity nor representativity. It imperfectly reports on the view of those who do not disclose, as all participants question the principle of secrecy, many being members of interest groups defending openness. Wider implications of the findings: Our results complement existing studies that emphasize the weight of age in donor conceived families’ experience regarding disclosure. Age alone cannot describe information-sharing practices that are embedded within their historical and social context as well as the family context and history. Results thus inform familial difficulties related to disclosure. Trial registration number Not applicable

Background The prevalence of autism spectrum disorders(ASDs) has increased 10 times over the past half century,while paternal and maternal age at pregnancy has alsoincreased. Studies looking for an association between paternalor maternal age at pregnancy and ASDs in offspring have notbeen conclusive.Objective To assess for possible associations between paternaland maternal age at pregnancy and ASDs in offspring.Methods This case-control study had 50 case and 100control subjects, each case was matched for age and genderto two controls. Case subjects were obtained by consecutivesampling of patients aged 18 months to 7 years who visited theDevelopmental Behavioral & Community Pediatrics OutpatientClinic and private growth and development centers from Januaryto April 2013, while control group were children of the sameage range and same gender who visited pediatric outpatientclinic at Sanglah Hospital mostly due to acute respiratory tractinfection, without ASDs as assessed by the DSM-IV-TR criteria.We interviewed parents to collect the following data: maternaland paternal age at pregnancy, child’s birth weight, historyof asphyxia, hospital admission during the neonatal period,pathological labor, maternal smoking during pregnancy, paternalsmoking, and gestational age. Data analysis was performed withChi-square and Fisher’s exact tests.Results Multivariable analysis showed that higher paternal ageat pregnancy was associated with ASDs in offspring (OR 6.3;95%CI 2.0 to 19.3; P 0.001). However, there was no significantassociation between maternal age during pregnancy and theincidence of ASDs. Asphyxia and paternal smoking were alsoassociated with higher incidence of ASDs in the offspring (OR10.3; 95%CI 1.9 to 56.5; P 0.007 and OR 3.2; 95%CI 1.5 to 6.9;P 0.003, respectively).Conclusion􀀃􀀳􀁄􀁗􀁈􀁕􀁑􀁄􀁏􀀃􀁄􀁊􀁈􀀃􀂕􀀗􀀓􀀃􀁜􀁈􀁄􀁕􀁖􀀃􀁌􀁑􀁆􀁕􀁈􀁄􀁖􀁈􀁇􀀃􀁗􀁋􀁈􀀃􀁕􀁌􀁖􀁎􀀃􀁒􀁉􀀃􀀤􀀶'􀁖􀀃in offspring by 6.3 times.
